Re: [jdt-core-dev] ITypeBinding - How to tell your at "java.lang.Object"

["Dirk Baeumer" <Dirk_Baeumer@xxxxxxx>]

Another idea is to compare the binding
with the binding returned from AST#resolveWellKnownType("java.lang.Object");

I suspect though that if the superclass is missing, the binding superclass
will also be null.

Tim,  Since java.lang.Object is the only genuine class without a
superclass, you could also use
      typeBinding.isClass() && typeBinding.getSuperclass()
== null

If one walks up the type hierarchy using ITypeBindings it appears a bit
difficult to figure out you are at the top (e.g., you get null from an
getSuperclass() method call).  The problem is "null" from
this call can
reasonably mean a few other things as well.

I've compared the fully qualified name to "java.lang.Object"
but I'm
wondering if there is a better way?

Should there be a "boolean isJavaLangObject()" method that returns
true
if the type is "java.lang.Object", and false otherwise?

Thoughts?

Take Care,
